\r
94 <div class="sectionbody">
\r
95 <div class="paragraph"><p>i3status is a small program (about 1500 SLOC) for generating a status bar for
\r
96 i3bar, dzen2, xmobar, lemonbar or similar programs. It is designed to be very
\r
97 efficient by issuing a very small number of system calls, as one generally
\r
98 wants to update such a status line every second. This ensures that even under
\r
99 high load, your status bar is updated correctly. Also, it saves a bit of energy
\r
100 by not hogging your CPU as much as spawning the corresponding amount of shell
\r
101 commands would.</p></div>

259 Use ANSI Escape sequences to produce a terminal-output as close as possible to
\r
260 the graphical outputs. This makes debugging your config file a little bit
\r
261 easier because the terminal-output of i3status becomes much more readable, but
\r

263 basic output-features (for example you only get 3 bits of color depth).

277 to define specific colors per module. If one of these directives is defined

278 in a module section its value will override the value defined in the general

\r
280 <div class="paragraph"><p>If you don’t fancy the vertical separators between modules i3status/i3bar
\r
281 uses by default, you can employ the <tt>separator</tt> directive to configure how
\r
282 modules are separated. You can either disable the default separator altogether
\r
283 setting it to the empty string. You might then define separation as part of a
\r
284 module’s format string. This is your only option when using the i3bar output
\r
285 format as the separator is drawn by i3bar directly otherwise. For the other

286 output formats, the provided non-empty string will be automatically enclosed

\r
616 <div class="dlist"><dl>
\r
617 <dt class="hdlist1">
\r
622 The alignment policy to use when the minimum width (see below) is not

623 reached. Either <tt>center</tt> (default), <tt>right</tt> or <tt>left</tt>.
\r
626 <dt class="hdlist1">
\r
631 The minimum width (in pixels) the module should occupy. If the module takes
\r
632 less space than the specified size, the block will be padded to the left
\r
633 and/or the right side, according to the defined alignment policy. This is
\r
634 useful when you want to prevent the whole status line from shifting when
\r
635 values take more or less space between each iteration.
\r
636 The option can also be a string. In this case, the width of the given text
\r
637 determines the minimum width of the block. This is useful when you want to
\r
638 set a sensible minimum width regardless of which font you are using, and at
\r
639 what particular size. Please note that a number enclosed with quotes will
\r
640 still be treated as a number.
\r
643 <dt class="hdlist1">
\r
648 A boolean value which specifies whether a separator line should be drawn
\r
649 after this block. The default is true, meaning the separator line will be
\r
650 drawn. Note that if you disable the separator line, there will still be a
\r
651 gap after the block, unless you also use separator_block_width.
\r
654 <dt class="hdlist1">
\r
655 separator_block_width
\r
659 The amount of pixels to leave blank after the block. In the middle of this

\r
706 <div class="sectionbody">
\r
707 <div class="paragraph"><p>While talking about two specific things, please understand this section as a
\r
708 general explanation why your favorite information is not included in i3status.</p></div>
\r
709 <div class="paragraph"><p>Let’s talk about memory usage specifically. It is hard to measure memory in a
\r
710 way which is accurate or meaningful. An in-depth understanding of how paging
\r
711 and virtual memory work in your operating system is required. Furthermore, even
\r
712 if we had a well-defined way of displaying memory usage and you would
\r
713 understand it, I think that it’s not helpful to repeatedly monitor your memory
\r
714 usage. One reason for that is that I have not run out of memory in the last few
\r
715 years. Memory has become so cheap that even in my 4 year old notebook, I have
\r
716 8 GiB of RAM. Another reason is that your operating system will do the right
\r
717 thing anyway: Either you have not enough RAM for your workload, but you need to
\r
718 do it anyway, then your operating system will swap. Or you don’t have enough
\r
719 RAM and you want to restrict your workload so that it fits, then the operating
\r
720 system will kill the process using too much RAM and you can act accordingly.</p></div>
\r
721 <div class="paragraph"><p>For CPU frequency, the situation is similar. Many people don’t understand how
\r
722 frequency scaling works precisely. The generally recommended CPU frequency
\r
723 governor ("ondemand") changes the CPU frequency far more often than i3status
\r
724 could display it. The display number is therefore often incorrect and doesn’t
\r
725 tell you anything useful either.</p></div>
\r
726 <div class="paragraph"><p>In general, i3status wants to display things which you would look at
\r
727 occasionally anyways, like the current date/time, whether you are connected to
\r
728 a WiFi network or not, and if you have enough disk space to fit that 4.3 GiB
\r
729 download.</p></div>
\r
730 <div class="paragraph"><p>However, if you need to look at some kind of information more than once in a
\r
731 while (like checking repeatedly how full your RAM is), you are probably better
\r
732 off with a script doing that, which pops up an alert when your RAM usage reaches
\r
733 a certain threshold. After all, the point of computers is not to burden you
\r
734 with additional boring tasks like repeatedly checking a number.</p></div>

\r
740 <div class="paragraph"><p>In i3status, we don’t want to implement process management again. Therefore,
\r
741 there is no module to run arbitrary scripts or commands. Instead, you should
\r
742 use your shell, for example like this:</p></div>
